SCRANTON - State Attorney General Kathleen M. Kane, who has already endured a tough year professionally, has filed for divorce, saying her marriage of 14 years is irreparably broken.

The complaint was filed Friday in Family Court in Lackawanna County, where Kane has lived in Clarks Summit with husband Christopher Kane and their two sons.

"This is a private matter that the attorney general has been enduring," Kane spokeswoman Renee Martin wrote in an e-mail. "She asks that the media respect the family's privacy."

Kane's divorce lawyer, Lynne Gold-Bikin, did not immediately return a message Saturday. Christopher Kane did not have an attorney listed in online records.

Kane has been on a political hot seat for several months.

Her investigation of a government e-mail porn scandal in the Attorney General's Office resulted in discipline for dozens of employees and played a big role in the resignation of a state Supreme Court justice.

She also took heat for quashing a probe - later revived by Philadelphia District Attorney Seth Williams - of lawmakers who allegedly took inappropriate gifts. And a grand jury is looking into whether Kane's office violated secrecy laws by improperly disclosing information to the Philadelphia Daily News.

In October, she suffered a concussion in a car accident.

Voters in 2012 elected Kane, a former county prosecutor, as the state's first female and first Democratic attorney general.

Her husband co-owns his family's trucking and warehousing company.
